Application filed June 4, 1914. SerialNo. 842,965.

T all whom 2'25 may concern:

Be it known that 1, "WILLIAM MANGIN, a citizen of the United States, residing at Raymond, in the county of Blackhawk and State of Iowa, have invented certaln n v and useful Improvements in Primers for Internsl'Combustion Engines, of which the following is a specification.

The present invention relates to a priming attachment for multiple cylinder internal combustion engines, and has for its ob ect to provide a device of this character wh ch embodies novel features of construction whereby it can be readily mounted upon an automobile and operated from the dashboard to instantly and simultaneously prime all of the cylinders of the engine.

A further -object of the invention s to provide a device of this character which is simple and inexpensive in its construction, which can be easily and quickly operated, which is not liable to get out of repair, and which can be quickly applied to any of the conventional types of multiple cylinder gasolene engines without necessitating any changes in the construction thereof.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a six'cylinder gasolene engine having the priming attachment applied thereto, portions being broken away and shown in section. Fig. 2 is an end view of the same. Fig. 3 is an enlarged side elevation of one of the branch priming pipes. showing the arrangement of the two superposed valves. Fig. 4 is a similar view looking at the same from a position at substantially right angles to that of Fig. 3. Fig. 5 is a sectional view through a portion of one of the branch priming pipes, showing the normal position of the valves with the lower valve closed and the upper valve open. Fig. 6 is a similar view showing the position assumed by the valves when priming the engine, the upper valve being closed and the lower valve being opened.

Corresponding and like parts are referred to in the following description and indi cated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the numeral 1 designatesthe upper portion of a six cylinder internal combustion engine which may be of any conventional construction, each of the cylinders being provided at the top thereof with a spark plug 2 and a priming cup 3. A gasolene tank 4 is mounted in a convenient position adjacent the engine 1, being shown in the present instance as applied to the front of the dashboard 5 immediately under the hood 6, and as held in position by suitable straps 7. Leading from the gasolene tank 4 is a main feed pipe 8 which extends longitudinally across the top of the engine 1, the free end thereof being shown as closed by a removable plug 9. A series of branch priming pipes 10 extend downwardlyfrom the main feed pipe 8 to the priming cups 3 of the several cylinders of the engine. These branch priming pipes 10 communicate with the priming cups 3 ata point below the usual valves 3 thereof so that the attachment does not interfere in any manner with priming the engine in the usual way should this become desirable.

Intel-posed in the length of each of the branch priming pipes 10 isa pair of superposed valves 11 and 12, which may be of any conventional construction, although for the purpose of illustration they are shown in the present instance as being of the rotary plug type. Each of the valves 11 is provided with an operating lever 18, and in a similar manner each of the valves 12 is provided with an operating lever 14. The several lower valves 11 are arranged in substantial horizontal alinement, as are also the several upper valves 12, and the several operating levers 13 of the lower valves are pivotally connected to the lower arm 15 of a bifurcated plunger 15, while the several levers 1 1 of the upper valve are pivotally connected to the upper arm 15 of the said bifurcated plunger. The rear end of the plunger 15 passes slidably through the dashboard 5 and terminates in a button or head 16, a coil spring 17 which surrounds the plunger being interposed between the dashboard and the head 16.

Under normal conditions the lower valves 11 are all closed and the upper valves 12 all open, as shown by Fig. 5. hen it is desired to prime the engine, the operator merely pushes upon the button or head 16 so as to slide the plunger 15 against the action of the spring 17, thereby simultaneously closing all the upper va ves 12 andopening all of the lower valves 11 so that the gasolene previously held in the branch priming pipes between the two valves is released and flows downwardly into the respective cylinders of the engine. As soon as the button 16 is released the spring 17 moves the plunger back into normal position so as to again close all of the lower valves lland open all of the upper valves 12, thereby permitting the portion of the branch priming pipes 10 between the two valves to be again filled with gasolene flowing from the tank 4 under the action of gravity. It will thus be obvious that in order to simultaneously prime all of the cylinders of the engine it is merely necessary for the operator to push inwardly upon the plunger 15 and then release the same.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

A priming device for internal combustion engines, including a gasolene tank, a main feed pipe leading therefrom, branch priming pipes erating levers of the upper nu es? plunger having a bifurcated end .w ich extends along all of the branch priming pipes, one ofthe arms of the bifurcation being pivotally connected to the operating levers of the lower valves while the other arm of the bifurcation is pivotally connected to the op valves, so that by sliding the plunger and releasing the same the lower valves will be temporaril opened and the upper valves closed to admlt of the gasolene confined in the branch riming ipes between the valves flowing dbwnwar ly into the respective engine cylinders.

In testimony whereof I afiix my signature in presence of two witnesses. 1
